Single Cylinder vs Double Cylinder – Pros and Cons

single cylinder vs double cylinder

Deadbolts are a critical component of any home security system. They provide an extra layer of protection against intruders and are often used in conjunction with other security measures such as alarm systems and surveillance cameras.

When it comes to deadbolts, there are two main types to choose from: single cylinder and double cylinder. In this post, we’ll explore the differences between the two, as well as the pros and cons of each.

Single Cylinder Deadbolts

When it comes to deadbolts, the single cylinder deadbolt is a popular choice among homeowners. It’s relatively easy to install, use and, most importantly, it’s cost-effective. In this chapter, we’ll take a closer look at the single cylinder deadbolt and explore its working mechanism, benefits, and potential downsides.

How does a single cylinder deadbolt work?

A single cylinder deadbolt is a type of lock that has a lock cylinder on the exterior of the door, which is operated by a key on the outside, and a thumb turn on the inside. When the key is turned, the deadbolt extends into the door frame, effectively locking the door. To unlock the door, you simply turn the thumb turn on the inside or use the key on the outside.

The benefits of using a single cylinder deadbolt

Single cylinder deadbolts are relatively easy to install and use, making them a popular choice among homeowners. They are also less expensive than double cylinder deadbolts, making them a cost-effective option. Additionally, the thumb turn on the inside of the door provides easy access to the lock, making it convenient for homeowners.

The potential downsides of using a single cylinder deadbolt

The major drawback of single cylinder deadbolts is that they can be easily unlocked from the outside if someone has a key or a tool to turn the thumb turn. This means that an intruder could potentially gain access to your home if they manage to acquire a copy of your key. This is a significant security concern, and it’s something that homeowners should be aware of when considering a single cylinder deadbolt.

Double Cylinder Deadbolts

Double cylinder deadbolts provide an extra layer of security as they can only be locked or unlocked from both the inside and the outside by using a key. They are often considered to be a safer option than single cylinder deadbolts because they can’t be unlocked with a tool or a lock pick. In this chapter, we’ll take a closer look at the double cylinder deadbolt and explore its working mechanism, benefits, and potential downsides.

How does a double cylinder deadbolt work?

A double cylinder deadbolt is a type of lock that has a lock cylinder on both sides of the door. This means that it can be locked or unlocked from both the inside and the outside by using a key. This provides an extra layer of security as the lock can’t be opened with a tool or a lock pick.

The benefits of using a double cylinder deadbolt

The primary benefit of using a double cylinder deadbolt is the added security it provides. Because the lock can only be opened with a key, it provides an extra barrier against intruders. Additionally, double cylinder deadbolts can also be used in areas that are prone to fires, as they provide an easy way to escape from the inside.

The potential downsides of using a double cylinder deadbolt

The major drawback of double cylinder deadbolts is that they can be difficult to unlock in case of an emergency. For example, if you’re locked inside your home and you don’t have a key, you will not be able to escape quickly. Additionally, double cylinder deadbolts can also be more expensive than single cylinder deadbolts, and they can be more challenging to install.

Comparison of Single vs Double Cylinder Deadbolts

When it comes to deadbolts, homeowners have the option of choosing between single cylinder and double cylinder deadbolts. Each type has its own set of benefits and drawbacks, and the right choice for you will depend on your specific needs and preferences. In this chapter, we’ll compare and contrast the two types of deadbolts in terms of security, ease of use, and cost to help you make an informed decision.

Security

When it comes to security, double cylinder deadbolts are generally considered to be the safer option. This is because they can only be locked or unlocked from both the inside and the outside by using a key, which provides an extra barrier against intruders. On the other hand, single cylinder deadbolts can be easily unlocked from the outside if someone has a key or a tool to turn the thumb turn.

Ease of Use

Single cylinder deadbolts are considered to be easier to use than double cylinder deadbolts. They are relatively easy to install, use and the thumb turn on the inside of the door provides easy access to the lock. On the other hand, double cylinder deadbolts can be difficult to unlock in case of an emergency, and they can be more challenging to install.

Cost

Single cylinder deadbolts are generally less expensive than double cylinder deadbolts. This makes them a cost-effective option for homeowners who are on a tight budget. However, the added security provided by double cylinder deadbolts may be worth the extra cost, depending on your specific needs.

Conclusion

In conclusion, the choice between a single cylinder and a double cylinder deadbolt ultimately depends on your specific needs and preferences. We recommend consulting with a professional locksmith before making a decision, to ensure that you are choosing the right type of deadbolt for your home. Remember that home security is crucial and investing in a good deadbolt will give you peace of mind and protect your family and property.
